SUPERTECH R BOOT Forged on the racetrack, the Supertech R is Alpinestars top-of-the-line road racing boot and benefits from the feedback of elite MotoGP and WSBK athletes. The latest version of the Supertech features a redesigned inner bootie constructed from 3D technical mesh that further reduces the boots weight while greatly enhancing breathability, comfort and feel.

Premium construction

* Front flex area is constructed with soft TPU mesh with shaped reliefs for abrasion resistance and enhanced fore and aft movement.

* Flexible accordion leather at Achilles allows natural movement.

* Top gaiter follows leg contour and is made of flexible high-grade synthetic leather reinforced with rubber for maintaining shape.

* Full length micro-fiber panel on inner side of the boot provides excellent grip and feel against the bike and protects from abrasion and heat.

* Lightweight rubber compound sole offers excellent grip and feel and allows for natural flex as the rider changes position and pressure on the foot-peg.

* Flexible, lightweight toe shifter allows feel for changing gears.

* Strategically positioned ventilation in heel and shin TPU, and soft TPU mesh on forefoot guides air through the boot.

* External TPU shin protection wraps around to outer calf and is engineered to spread and dissipate impact energy across the entire surface while remaining compact. Vented sections promote airflow into the boot.

* Separate inner brace works with outer boot to form a protective system.

* Replaceable TPU heel plate slider protects from impact and reduces friction in the event of a crash.
